The present study disentangles 2 sources of the congruence sequence effect with masked primes: congruence and response time of the previous trial (reaction time [RT] carry-over). Using arrows as primes and targets and a metacontrast masking procedure we found congruence as well as congruence sequence effects. In addition, congruence sequence…

The present study aimed to investigate whether well-established associations between action and language can be altered by short-term upper limb immobilization. The dominant arm of right-handed participants was immobilized for 24 hours with a rigid splint fixed on the hand and an immobilization vest restraining the shoulder, arm, and forearm. The…

In the present study, we compared the processing of both conventional and novel metaphors by deaf versus hearing young adults. Eighteen deaf participants with severe-to-profound hearing loss and 18 controls matched for age, sex, and years of education were presented with word pairs of 4 types (literal, conventional metaphors, novel metaphors, and…

Purpose: Research on language planning in adult stuttering is relatively sparse and offers diverging arguments about a potential causative relationship between semantic and phonological encoding and fluency breakdowns. This study further investigated semantic and phonological encoding efficiency in adults who stutter (AWS) by means of silent…

We propose the use of a smartphone based time-lapse and slow-motion video techniques together with tracking analysis as valuable tools for investigating thermal processes such as the response time of a thermometer. The two simple experimental activities presented here, suitable also for high school and undergraduate students, allow one to measure…

Background: Concussion education for coaches is being increasingly recommended by leading sports organizations, yet the effectiveness of available materials has not often been assessed. This study evaluated the impact of the National Collegiate Athletic Association's (2017) publication: "Concussion safety: What coaches need to know" (the…

The Rapid Assessment of Cognitive and Emotional Regulation (RACER) is a tablet-based assessment tool for children that measures executive function (EF) skills. Instructions that are brief and visually presented; game-like tasks are designed to easily engage children regardless of literacy level and variable test administration settings. RACER…

Students' executive functions (EFs) are linked to school success. Although school-age children spend much of their time interacting with peers, few studies have explored how children's classmates may promote EF development in elementary school. In this study, we test whether mean levels and variability in classmates' EF skills are associated with…

Purpose: We investigated whether rhythm discrimination is mainly driven by the native language of the listener or by the fundamental design of the human auditory system and universal cognitive mechanisms shared by all people irrespective of rhythmic patterns in their native language. Method: In multiple experiments, we asked participants to listen…

During problem-based learning sessions, undergraduate students were tasked with answering chemistry-related questions using clicker-handset technology in which the last response made by each handset would override any previous vote. The benefits, if any, of showing cohort responses from clicker questions during versus after polling were explored.…

In this commentary, Kuhn and Ranger hypothesize that most people are aware that talent does not guarantee success in case one is lazy. This is also true for the performance in achievement tests that depends on, among other factors, achievement potential (ability) and willingness to achieve (test-taking motivation) of the test taker. They add that…

A new and very interesting approach to the analysis of responses and response times is proposed by Goldhammer (this issue). In his approach, differences in the speed-ability compromise within respondents are considered to confound the differences in ability between respondents. These confounding effects of speed on the inferences about ability can…

We report on five experiments investigating response choices and response times to simple science questions that evoke student "misconceptions," and we construct a simple model to explain the patterns of response choices. Physics students were asked to compare a physical quantity represented by the slope, such as speed, on simple physics…

Greater cognitive ability in childhood is associated with increased longevity, and speedier reaction time (RT) might account for much of this linkage. Greater bodily symmetry is linked to both higher cognitive test scores and faster RTs. It is possible, then, that differences in bodily system integrity indexed by symmetry may underlie the…

The education of gifted children is of considerable interest. The present study focused on the effect of enriched education on intellectually gifted children's attention. In the present study, 7-12-year-old children completed seven tests of attention (alertness, focused attention, divided attention, attentional switching, sustained attention,…
